Simple Squamous Epithelial Tissue
Simple Columnar Epithelial Tissue
Psuedostratified Ciliated Columnar
Stratified Cuboidal Epithelial Tissue
Multiple Layers of Cells
The large round cells allow it to slide or move past eachother. It also allows the tissue to stretch.
Cuboidal and columnar cells have large, open cytoplasms. Which of the functions of epithelial tissue are supported by having such big cells?
Arrangement and Shape
How are epithelial tissues named?
It connects the epithelium to the rest of the body. It also provides structure (bone), stores energy (fat), and transports material (blood).
What is the primary function of connective tissue?
matrix is the extracellular fibers and ground substance of a connective tissue. Some tissues have more matrix because the cells and fibers are not as tightly packed.
What is matrix? Why do some tissues have more than others?
Collagen is strong and flexible and resists force in one direction. It is stronger than steel when pulled. Ligaments and tendons are collagen fibers.
What do collagen fibers do for a tissue?
If there is limited blood supply it means the nutrients and supplies to heal an injury in this area are not that readily available.
Tendons, ligaments, and cartilage have limited blood supply. Explain how this might affect the ability of these tissues to heal after injury.
Smooth muscle tissue
What kind of muscle would you find in your stomach?
Smooth muscle can contract on their own. Smooth muscle tissue has no striations.
How is smooth muscle structures different from that of skeletal and cardiac muscle?
Skeletal fiber muscles do not contract unless stimulated by nerves and the nervous system provides voluntary control over their activities.
Why do we say that skeletal muscle is voluntary?
Nervous tissue conducts electrical impulses. It also rapidly senses internal or external environment. They process information and controll responses.
What is the function of nervous tissue?
Neurons are specialized for intercellular communication through changes in membrane potential and synaptic connections. Nerves refer to a structure made up of many neurons.
How is a nerve different from a neuron?
